ASD FieldSpec 3 spectrometer covering the 0.4-2.5 µm domain (ASD Inc.).

ISEP (Imageur Spectral pour l’Exploration Planétaire) is a dedicated laboratory wide field spectrophotogoniometric imaging facility set up at IRAP, Midi-Pyrénées Observatory, Toulouse, France (Pinet et al., 2001, Cord et al., 2003, Souchon et al., 2011).
This instrument covers the 0.4-1.0 µm domain and operates under either natural solar or artificial extended light source and characterizes the optical response of geological targets from 10 mm x 10mm to 20 cm x 20 cm size, ranging from controlled powders to complex slab rock samples.
